The hostile takeover of Hell is bearing forbidden fruit all over Earth, as their aggressive new customer-service campaign makes rapid gains in the battle for market share...over us! The reason gods and demons grant humans wishes is the energy they gain from the strength of our desires...a cosmic competition kept stable only when both sides are equal, and by linking each god to a demon through the Doublet System. But Belldandy, herself, imbalances it through her link to the human being she loves. If order is to be restored, it will require not only her help, but that of the goddesses Peorth and Lind...all to put Hild, the deposed lord of demons, back on her throne!

College life is never easy . . . all right, sometimes it is, but never at Nekomi Tech! No sooner do Keiichi and Belldandy solve the mystery of the Phantom Racer, then they get entangled in the schemes of Professor Morozumi. Better known on campus as "Dr. Moreau" for his obsession with making machines walk on two legs, this mad scientist will stop at nothing to pursue his dream . . . including kidnapping Banpei''s "girlfriend," the Welcome Robot!

Ever since a cosmic phone call led to five literal young goddesses Belldandy, Urd, Skuld — and, like occasional vowels, Peorth and Lind — to live in college student Keiichi's residence, his personal life has been turned upside down, sideways, and sometimes even into strange dimensions! After the drama of the familiar, we return to the comedy of the even more familiar, as Oh My Goddess! goes back to school — Nekomi Tech, that is, only to find the campus festival tradition has lost none of its lunacy. Tamiya and Otaki are bringing all their idol graces to the stage in a karaoke contest, with a special surprise entrant from way back... versus the indescribable voice of Belldandy! Plus your fan art and letters!

Peorth is back! ... but in a pint-sized version of her true self. The demon, Velsper, who put her in this situation is now a kitten and isn't much help. How will she ever get back to her normal size?

Sora Hasegawa faces off against Keiichi in a crazy go-kart race through campus to settle who will lead the Motor Club. Keiichi has the experience... but Hasegawa is being trained by Belldandy! No more gap on your bookshelf, Oh My Goddess! fans — Volume 20 completes the run of "classic" OMG! series, previously released flopped, now all reissued in Japanese reading order.

Be confident. Be gorgeous. Be glamorous. The tips and tricks in this book will help girls reveal the goddess inside.

Mokkurkalfi, Hell's mistress of machines, is the next door warden Keiichi and the goddesses must pass. With her mechanical skills, she's the natural opponent of Skuld...but unlike her, Mokkurkalfi has no love for her inventions, instead setting them against each other viciously, to retain only those strongest in battle! Will so ruthless an approach to robots be the defeat of the youngest goddess...and of them all?
